Designed by Ronan and Erwan Bouroullec, the Quindici  Armchair is formed from precisely angled moulded ash panels supported by distinctive T-shaped armrests, creating a sculptural yet understated silhouette that balances structure, comfort and visual lightness. As Mattiazzi’s first upholstered lounge chair, it combines a solid ash frame with generous cushioning and a reclined seating posture, expressing the Bouroullecs’ interest in reducing furniture to clear architectural elements while maintaining warmth and ergonomic support.
